AUTO CAD 2D TUTORIAL


            If you are looking for a free tutorial on auto cad 2D you have come to the right place.
this auto cad 2D will teach you step by step on working with auto cad 2D environment.
            In order to become effective and efficient in using a CAD system, we must learn to create
geometric entities quickly and accurately. In learning to use a CAD system, lines and
circles are the first two, and perhaps the most important two, geometric entities that one
should master the skills of creating and modifying. Straight lines and circles are used in
almost all technical designs.

             In examining the different types of planar geometric entities,
the importance of lines and circles becomes obvious. Triangles and polygons are planar
figures bounded by straight lines.
Ellipses and splines can be constructed by connecting arcs with different radii. As one gains some experience in creating lines and circles, similar procedures can be applied to create other geometric entities.
In this chapter, the different ways of creating lines and circles in Auto Cad® 2013 are examined.
              The following are covered in this tutorial;
